以横县果蔗当家品种拔地拉(俗称黑皮果蔗)为对照种,对桂果蔗1号进行2年多点比较试验。试验结果:桂果蔗1号株高332.0cm,比对照种312.0cm高20.0cm;茎径为3.89cm,比对照种的3.87cm大0.02cm;667.7m~2产蔗13223kg,比对照种的11589kg增产14.10%;商品蔗产量12949.6kg,比对照种的10438.4kg增产24.06%,商品蔗率高达97.93%;其节间长度较长,商品性较佳,长度8.0~13.9cm的节间占总数的82.29%,拔地拉只有70.47%,对商品性影响较大的极短节≤5.9cm中只有0.87%,拔地拉高达4.19%;植株上中下大小均匀,茎粗下、中部相差0.24cm,上、中部相差0.06cm,拔地拉上部较小,表现出早衰现象;蔗糖分略高于拔地拉;产值较高,达19305.0元/hm~2,比拔地拉的14945.9元/hm~2增收29.17%,差异达极显著水平。结论:桂果蔗1号农艺性状、商品性状、产值等均优于拔地拉,可在横县进行大面积推广应用。
Taking Hengdian (commonly known as black fruit and cane) as the control species, the comparative experiment was conducted on Guiyang sugarcane 1 for more than two years. The results are as follows: The height of Gui Gua Cane 1 was 332.0 cm, which was 20.0 cm higher than that of 312.0 cm. The stem diameter was 3.89 cm, which was 0.02 cm larger than the 3.87 cm of the control. 13223 kg of 667.7 m ~ 11589kg and 14.10% respectively. The yield of commercial cane is 12949.6kg, which is 24.06% higher than 10438.4kg of the control and 97.93% of the commercial cane. The internode length is longer and the commerciality is better. The total length of the internodes with length of 8.0 ~ 13.9cm Of the total, 82.29% of the total, and only 70.47% of the tabula, and 0.87% of the very short segments ≤5.9cm, which had a great influence on the commercial value. The average upper and lower plant sizes were 4.19% cm, the upper and the middle of the difference 0.06cm, pull the upper part of the smaller, showing the phenomenon of premature aging; sucrose slightly higher than the pull out; output value higher, reaching 19,305.0 yuan / hm ~ 2, than the pull of 14945.9 yuan / hm ~ 2 increased 29.17%, the difference reached a very significant level. CONCLUSION: Guiguang sugarcane No.1 agronomic traits, commodity traits and output value are superior to that of pullira, which can be popularized widely in Hengxian County.
